To all 'whom it may concern: l 'Be it known that I, I `L0Ri3iri` Io'sET, -a citi- I zen of the United States, residing at Wadena,

in the county of Wadena and State of Minneseta, have invented a new and useful Pipe# VWrench, of which the 'following is a specification. y

vThis invention relates to gripping devices,

fand more particularly to that 'type of wrenches adapted to encircle round objects, such as pipes, fruit jarcovers, and the like, and has for its objectto provide a smooth gripping surfacesuch as will not mutilate'or -fotherwise-defacegthe surface ofthe object to be turned It is well'known that with most Wrenches .used in pipe fitting, the gripping jaws are serrated, and after a pipe has .been threaded into an elbow or joint with such' awrench, the

Amarks leftonthe surface of the pipe render it unsightly.: This is especially so .Withinickel "l plated defect -25 pipes used injbathr'oom fittings The resentinvention aims to remedy this y employing` 'aj resilient or flexible 'member having smooth'contacting surfaces adapted to encircle a pipe or other round ob-I ject and either tighten or loosen the same Without markin With these and otheriobjects in view, asi

will more 'fully hereinafter a ear, theinven tion consists 1n certain nove eatures of construction and arrangementof parts, 1 hereinj understood that varlous changes in the form, A

proportions, lsize and minor details of the structure may be made without departing from the'spirit or sacrificingA any of the ad- 40 I l 4, fln' the accompanyin drawings:.-.Figure 1 -ls` a perspective view o the device-equippedl for turning; pi es'and the like. .A side view'of t le same. tive view 'showing the T t'urning heavy steam'pi es and the l Similar.`v numerals o 'reference are emfl 'ployed te indicate corresponding throughout the'- several gures of the raw- ,1ngs. A handle. 17' which'may be formed from Wood, iron, or other suitable material., isA proafterv fully described, illustrated inthe accompanymg drawings, andl `particularly pointed out in the appended claims, it being vantages o the invention.

Fig. '2 1s a device equi ed for tia.

an intermediate circular portion adapted to form a smooth grip for the hand of the o erator. Adjacent the opposite end v3, an eX-- Figa isa perspecj l ltending forwardly from the circular ortion 1s an approximately rectangular portlon, the front` face 4 of which is beveled at the end, said beveled end forming a bearing surface 9, thefunction of which will appear later.` The front face 4-is intermediately provided with a perforation extending `transversely through the opposite face'formin a seat for the screw 5, the threaded end of w ichteX-tends beyond the face 4, vand on this end v"is threaded a thumb nut 6.v A flexible member 7, preferably formed of soft steel or'other suitable material,l is rovided with perforations 8, and one end of t 's member is secured to the face 4 and rovided with a perforation registering with tlie perforation for a screw 5.

When 1t is desired to usethe device for turning fruit jar covers, small pipes, and the like, the free end of the member is passed around the object to be turned, and the member adjusted toa snug iit. The free end then is' brought down and over the face 4 and is secured thereto by the screw 5, entering one of the perforations 8. When the device is now turned by means of the handle, the shoulder 9 will bear against the outer face of the member 7, and as the pressure on the handle increases the member will vbe forced further over on the shoulder 9. It is obvious that as this is done, the ordinary circle formed by the adjoining ends of the member will be contracted, with consequent increase of friction between the members and object to be turned resulting in looseiiiing'or tightening the latter, as the case may. be.

In the modification shown in Fig. 3, a chain 10.is used instead of the band 7, and

this form of the device is intended for use kwith large steam pipes and the like. Instead of the screw 5 andnut 6, in this case there is are more or less apt to get out of .order or broken.- The` present device `is com aratively ineirpenslvev ,tov manufacture, re uces the number of parts to the minimum, and at the same time resents a device adapted for use on the `lig test and heaviest forms of pi e.

IlVhat is claimed is 1. A gripping deviceembodyirig a handle a large number ofparts are employed which.

10 provided with site flat faces, one of said faces terminating' having opposite faces, one of said faces terminating in a beveled surface 'at one end of the handle, a member provided Withopenings, and a means adapted to pass through 5 the openings and serving to secure themember on one face of the handle so as to bring the one face of the member t0 bear on the beveled surface.

2. A gripping device embodying alhandle an opening and having oppoin a beveled surface at one end of the handle, a flexible member having a plurality of openings adapted to 'be brought the opening of the handle, and a member adapted to enter the said openingsr and serving to secure the'lexible member on one face to register with l of the handle so as to bring the one face of the y
